.IMPROVEMENT IN TRACK-CLEARERS.

Specification forming part of Letters Pat Be it known that we, ELI PERRY and AN- i DREW J. MANLEY, of Fox Lake, in the county of Dodgeand State of Wisconsin, have invented certain new and useful Improvements A inSnow-Plows 5 and We do hereby declare that the following is a full, clear, 'and exact description thereof, which lwill enable vothers skilled in the art to which it pertains to make and use the same, refereucebeing had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification. Y

The object ofthe present invention is to construct a snow-plow which is especially designed for removing the snow fromY heavy drifts, where an ordinary snow-plow is `entirely useless.

'//Tle principal feature of the invention consists in the employment of a horizontal vertically-sliding knife or platform, which is lo-` cated between two stationary side cutters at the front end of a car, and in such relation to a sliding vertical cutter that when the plow is forced into a snow-drift the horizontal and side cutters will excavate or cut out a block of snow, which is then separated from the main mass by the descending vertical cutter, after which the horizontal and vertical cutters are simultaneously raised to bring the snow opposite lateral discharge-chutes or troughs.

rlhe invention also consists in the provision of a laterally-movable knife or spade, which is located between the stationary side cutters, and in rear of the sliding vertical cutter, so as to first cut the mass of snow elevated by the horizontal cutter into two parts, after which it is moved in opposite directions from the center of the plow, so as to deliver the snow to the discharge chutes or troughs, which con- 4 /,---vey it to the side of the track or road. `\";y/I the accompanying drawings, Figure l represents a vertical longitudinal section of a snow-plow embracing my invention, showing the vertical cutter elevated; Fig. 2, a similar section, showing the horizontal platform cutter elevated; Fig. 3, a front elevation, with the parts in the position shown in Fig. l 5 and Fig. 4, a transverse section, showing the action of the laterally-actingspade.

In the drawing, A denotes a platform or ent No.' lsmcoadated september 26, 1876; application' ined .'March21,`1s76.

B are vertical standards, which rise from the. front of. the car, and" formaframe forl supporting the entire plow mechanism, and guiding the movementof the movable parts; To the side of each outside standard isA attached a vertical side cutter-plate, C, the front edge of which is made sufficiently `sharp to readily cut its way into the snow. Between the stationary side cutters C there is located a horizontal cutter or platform, D, the forward edge of which terminates alfthe front edges of the side cutters. d'Said horizontal ,cutter isattached by means of a rear vertical the vertical standards B. A vertical knife,

into operation the horizontal cutter is located at the bottom of the side cutters, and the vertical knife is raised to such an extent as will or separation of a mass or block of snow by the horizontal and side cutters. snow is removed from the drift by the forward movement of the plow, and is forced into the space or chamber formed between the cutters G is then caused to descend, so as to cut through the snow and separate the excavated portion from the main mass. The horizontal cutter D and the vertical knife are then raised, together with the snow, until the latter is in line with a discharge-opening and chutes I at the sides of the plow. The excavated mass of snow is in the form of a quadrilateralblock', and as it is elevated it is cut into two parts by means of a centrally-located cutter or spade, J, which is carried by and extends in a downward direction from a horizontallysliding bar K. Said bar runs between two guide-rail'L, which` extend across the front portion of the plow, and are attached to the extension or plate, E, to sliding strips or bars F, which are itted in ways or tracks between G, extends the entire width of the horizontalI cutter D, and is madeto slide up and down' on guide-rods H rising from the side cuttersl C, loops or tubes a on the knife encircling the guide-rods.

Other means for reciprocating the spade may be resorted to-,as, for

example, a rack-bar and pinion-shaft.

The horizontal cutter and snow-elevating platform is raised and lowered by means of belts P, which are attached to the opposite ends of the bars F, and pass around a drum or pulley shaft, Q, at the rear side of the supporting-standards B. Said shaft-Q carries a central spur-wheel, d, which gears into a spurwheel, e, on a hand or crank shaft, f. The

lvertical cutter G is lowered by force by means of a belt, 9v,` and crank-shaft h, and an additional belt, i, is provided for raising the knife when it is preferred to do it by hand, and not by the movement of the horizontal cutter. `Rack-bars and pinions, and other mechanical .expediente are in all instances. to be employed when the belts and pulley-shafts are not used. 'I'.lhedischarge chutes or troughs may also be attached by hinges, so that they can be turned down or lowered in passing over bri d ges,
